A calibration method for bolt tensioners is presented. According to the theory of Newton′s Third  Law, the calibration device is researched and designed to calibrate the bolt tensioners. The measurement error and repeatability analysis and uncertainty evaluation show the linearity is good. Considering the measurement error is within ±1%, which meets the calibration requirements for bolt tensioners, the designed calibration device is capable to carry out the calibration work for bolt tensioners.
